75 YEARS OF THE E.O. PATON ELECTRIC WELDING INSTITUTE OF THE NAS OF UKRAINE Rapid development of econ - omy of the Russian Empire at the end of the 19th century re - quired highly qualified engi - neering staff. The Kiev Polytechnic Institute (KPI) was founded in Kiev in 1898 to educate such specialists. The first rector of KPI Prof. V.L. Kirpichov invited young scien - Prof. Evgeny O. Paton tists to work as teachers at the Institute. Among them was Evgeny Oskarovich Paton, who at that time already was a known scientist in the field of bridge construction. During the years of his work in Kiev, Evgeny Paton designed and constructed many unique bridges and other structures, and completed a number of fundamental studies on bridge construction. In 1904 he became the Head of the Bridge Chair at KPI. In 1929, Evgeny Paton was elected a full member (academician) of the All-Ukrainian Academy of Sciences, which led to accelerated development of struc - tural mechanics, metallurgy, materials science and electric welding in Ukraine. New academic institutes were founded, thus launching active R&D activities in the field of technical sciences. E.O. Paton initiated setting up of the welding laboratory at the Chair of Engineering Structures for comprehensive investigations of welded structures and metallurgical processes, welding metals science and physics of the arc discharge with subsequent develop - ment of welding equipment, consumables and tech - nologies. To address all these challenges, the Electric Welding Institute was founded in 1934, and E.O. Pa - ton was appointed the director of the Institute. Mechanisa - tion and automation of welding were considered to be among the most important tasks of the Institute from the very first years of its existence. In 1939--1940, the Insti - tute headed by E.O. Paton de - veloped the method for auto - matic submerged-arc welding and unique technology for automatic welding of ar - moured bodies of tanks, air bombs and artillery sys - tems. During the Great Patriotic War the staff of the Institute continued the research activity under factory conditions. In 1942, V.I. Dyatlov discovered the phe nomenon of self-regulation of electrode melting in sub merged-arc welding. Investigations into this phenome Prof. Boris E. Paton - - - non by B.E. Paton, together with A.M. Makara, P.I. Sevbo and M.N. Sidorenko, were used to develop port - able, simple and reliable automatic welding devices. Automation of the welding process made it possible to increase within the short time period the output of tanks and substantially improve the quality of the welded joints. Tank T-34 manufactured by Uralvagon zavod in Nizhny Tagil and other factories of the coun - - try was recognised by experts to be the best mediumweight tank of the Second World War. Lives of many thousands of tank crews were saved thanks to its reliable welded armour. In 1943, E.O. Paton was awarded the title of the Hero of Socialist Labour of the USSR for his contribution to increase in defence The first building of the E.O. Paton Electric Welding Institute 2 9/2009
